Since I own one, I would know and I've done my research. The only way to get a sport suspension on an xDrive is to order the DHP. If you check further, you'll find out that xDrive deletes the 704 suspension.

Junkyard is correct. This has been addressed many times and unfortunately BMW USA website is in error and it seems many CAs are misinformed. xDrive's DO NOT get sport suspension on sportline or msport. You can add adaptive suspension to get a sportier ride in sport mode but this is not standard. BMW needs to make this clearer.
